Not only the first time users even the umpteen years old couples get hit by this question often. But the harsh truth is that nothing in this world is 100% efficient or effective. Even the earth has a hole in its protective layer. So the efficacy of the condoms is determined by a couple of factors which will be discussed in this article.
The condoms are 98% effective. Shocking right? It means that the condoms are 98% effective only when used impeccably. But we, human, aren't perfect to do so when she is waiting naked for you. So in reality, condoms are only 85% effective. In other words, out of 100 couples who use condoms to prevent pregnancy 15 couples will get pregnant anyway. Generally, the failure rate of the condoms is extrapolated to be around 15% which is solely due to the errors made by us. Condoms failure involves a couple of factors.
The better you are about using condoms correctly every time you have sex, the better they’ll work. But there’s a small chance that you will get pregnant even if you always use them the right way. So be careful while using it when you purchase condom online.
So what exactly goes wrong and what causes condom failure?
Inappropriate condom size - A condom could slip off or break inside the vagina during physical intercourse if it doesn't fit correctly, as a result of which the sperms get to reach the ovum.
Quality - It is always recommended to buy condoms that are approved by the FDA. If you don't you might end up using a condom with tiny holes or low quality that could break easily.
Trapped Air - To avoid breakage or slip off, condoms should be worn perfectly. If not, the incorrectly worn condom will have air trapped inside which will, then, cause condoms to break or slip off while having vaginal intercourse.
Delayed Retrieval - The sperms can reach the eggs if you don't take out your condom-wrapped penis after ejaculation.
Feeling Decreased sensation - Most of the couples feel that condoms decrease sexual pleasure and they opt to use it just right before ejaculation. Most of the time, this won't help because there will be a little amount of sperm in the male's urethral mucus that comes out right before ejaculation. That little amount of sperm can reach the female egg and results in pregnancy later.
